Not only is aluminum (aluminium if you are British) recycled frequently, it is recycled economically. Even more, when aluminum replaces heavier steel products in transportation, it saves energy for the life of the vehicle because it takes less energy to move less mass. Although aluminum is not as good a conductor as copper, it is used in transmission of electricity because using thicker aluminum wires still weighs less than an equivalent amount of copper to do the job. This saves money on the actual wires and allows the towers that hold the transmission lines to be less massive. This is fine in places where the air cools the wires. Do not use aluminum in household wiring because it will overheat inside walls and may cause a fire.

Think wind and sun. But this will get you thinking possibly the other way due to recycling: "Water can be considered a renewable material when carefully controlled usage, treatment, and release are followed."
